“…In [26][27][28][29][30][31][32], jump conditions and are known and are used to derive the linear combination of the values of the points across the interface Γ. However, in this paper, we need to construct and for each interface cell Δ ∈ Λ 2 from the points with known value across the interface Γ and − on Ω − and then calculate the linear integral…”

“…The idea of applying interface problem solvers into noninterface problems is completely new. The nontraditional finite element method is originally developed in [26][27][28][29][30][31][32] for solving elliptic or elasticity equations with sharp-edged interfaces. This method uses non-body-fitting Cartesian grids and uses different basis for the solution and test function; its linear system is independent of jump condition.…”

“…These methods were extended to the case of Crouzeix-Raviart P 1 nonconforming finite element method [12] by Kwak et al [18], and to the problems with nonzero jumps in [7]. Some related works on interface problems can be found in [5], [16], [17], [19], [22], [23], [26].…”

“…In [13][14][15][16], we developed a nontraditional FEM with non-body-fitting grids for elliptic equations with smooth/sharpedged interfaces and ½u -0 and ½b @u @n -0. It can deliver (almost) second-order accuracy in L 1 -norm for both smooth and sharp-edged interfaces [14][15][16].…”
